Water collecting device with gradient hydrophilic and hydrophobic performance and application thereof

Abstract

The invention belongs to the technical field of water collecting and energy conservation, and particularly relates to a water collecting device with the gradient hydrophilic and hydrophobic performance and an application thereof. The water collecting device with the gradient hydrophilic and hydrophobic performance comprises gradient pore hydrophilic porous foam, hydrophobic porous foam, a collecting tank, a protective cover and a porous foam fixing structure; wherein the protective cover is filled with the gradient pore hydrophilic porous foam and the hydrophobic porous foam; two spaces are arranged on the two sides of the hydrophobic porous foam correspondingly; the front space is an interval gap between the hydrophobic porous foam and the gradient pore hydrophilic porous foam, and the width of the front space is in a millimeter scale; the rear space is provided with the collecting tank; and the hydrophobic porous foam is suspended through the porous foam fixing structure, so that the interval gap on the front side communicates with the collecting tank.

Description

technical field [0001] The invention belongs to the technical field of water collection and energy saving, in particular to a water collector with gradient hydrophilic and hydrophobic properties and its application. Background technique [0002] One-third of the earth's non-salt water is scattered in the air, and collecting water in the air is one way to solve the problem of water shortage. Generally, there are three main methods of water collection: groundwater evaporation, water collection by plant evaporation, and water collection by trapping fog in the air. For dry and water-poor areas, where vegetation is scarce and groundwater is scarce, the third type of mist trapping and water collection has become the main freshwater collection method. [0003] In recent years, based on the understanding of nature and the development of bionic science and technology, scientists have conducted research on a Namib beetle in the arid desert, and proved that the complex "pockmarks" and...

Problems solved by technology

The solar water droplets designed by Ap Verheggen in 2015 also use solar power to condense water in the air on low-temperature surfaces, and the water droplets are collected inside the droplets under the action of gravity; this structure is still in concept, and its performance is limited by the efficiency of solar cells and power

Finally, at present, most of the key components of water collectors use surface modification methods to endow them with the function of condensation and mist collection, such as coating micro-nano particle structure, local hydrophilic and hydrophobic surface coating treatment, etc.; Structural material, coupled with its structural characteristics to play a better water collection performance
